About me

I am a Research Specialist at the Center for Cervical Cancer Elimination since 2024. I have been researching cervical cancer topics since 2015, and SARS-CoV-2 since 2022. I maintain the quality registries for cervical cancer prevention and SARS-CoV-2.

My research in cervical cancer revolves around screening strategies and improvements for healthcare prevention and sentinel systems, such as risk based recall schedules or optimal contact windows for best participation. On SARS-CoV-2 I primarily look at long term consequents and analyses, such as "long-COVID" persistent symptoms or healthcare burden.
